Radio meteors December 2019

The graphs show both the daily totals (Figure 1) and the hourly numbers (Figure 2) of “all” reflections counted automatically, and of manually counted “overdense” reflections, overdense reflections longer than 10 seconds and longer than 1 minute, as observed here at Kampenhout (BE) on the frequency of our VVS-beacon (49.99 MHz) during the month of December 2018.

During this month there were few local disturbances, no registered “sporadic E” (Es) nor was there lightning activity.

Highlights of the month were of course the Geminids. – see also Figure 3 for the period 7-17 December 2018. The shower was very interesting, with as expected a large number of underdense and short overdense echoes, but with a rather unexpected outburst of longer overdenses on December 14/15th. Figures 4, 5 and 6 are typical examples of both.

The Ursids were certainly interesting but much less numerous than e.g. in 2017, with as usually an fair number of overdense echoes which is mainly reflected in the daily totals.

Also the beginning of the month was rich in reflections, both underdense and overdense, but these will have to be investigated further along with the rest of the month.
